Function definitions are not permitted.... trying to make an FFT thing
I'm trying to get this working
close all
clear all
function[X,freq]=positiveFFT(x,Fs);
N=length(x);
k=0:N-1;
T=N/Fs;
freq=k/T;
X=fft(x)/N;
cutOff = ceil(N/2);
X = X(1/cutOff);
freq = freq(1:cutOff);
Any ideas?

I think it might be right. Just discovered that the function line has to be the top line of code otherwise it doesn't work.

I think instead of this
X = X(1/cutOff)
you meant this
X = X*(1/cutOff);

You should think of "clear all" as being like trying to reprogram the fuel injector computer on a car: if you don't have years and years of training, you probably should not even be considering doing it.
